In a landmark moment for African infrastructure, Algeria has cemented a crucial piece of its economic future with the completion of the longest railway bridge on the continent. This monumental structure is the centerpiece of the strategic 950-kilometer western mining line, linking Béchar to Tindouf and the immense Gara Djebilet iron ore deposit.
A Pillar of Progress: The Final Beam in Place
According to a statement from the National Agency for Railway Studies and Investment Monitoring (ANEESIF), Tuesday marked a historic milestone. Construction crews successfully placed the final pre-stressed concrete beam on the grand viaduct over the Daoura Valley, officially concluding the primary structure of this engineering marvel.
Stretching an impressive 4,111 meters (over 2.5 miles) across the desert landscape, the bridge is not just a feat of length but a testament to modern engineering and determination.
By the Numbers: An Engineering Colossus
The scale of this "exceptional structure" is brought to life by its staggering statistics:
Concrete: 100,154 cubic meters of reinforced concrete.
Superstructure: 117 supporting decks, formed from 1,170 pre-stressed concrete girders.
Support System: Resting on 116 supporting piles (piers) and 1,432 foundational piles (pioux) driven deep into the ground.
These figures underscore the bridge's role as a critical, load-bearing artery designed to support heavy-haul freight trains for decades to come.
Strategic Significance: More Than Just a Bridge
This achievement is far more than a record; it is the key that unlocks one of Algeria's most vital economic projects. The primary mission of this railway is to connect the remote Gara Djebilet mine to the national network. Gara Djebilet holds an estimated 3.5 billion tons of iron ore, representing one of the world's largest untapped reserves.
For Algeria, this connection is transformative. It will:
Fuel Industrial Growth: Enable the efficient transport of raw materials to steel plants and processing facilities, reducing dependency on imports.
Boost Exports: Create a reliable and cost-effective route for future iron ore exports.
Develop the Region: Integrate the remote southwestern regions into the national economy, fostering local development and creating jobs.
Overcoming the Desert's Challenge
Constructing a project of this magnitude in the harsh Sahara presented unique obstacles. Engineers and workers battled extreme temperatures, fierce winds, and complex logistical chains to transport materials and equipment across vast, uninhabited terrain. The successful completion of the Daoura Viaduct stands as a triumph over these environmental and logistical challenges.
A Stepping Stone to the Future
With the longest bridge now complete, Algeria accelerates towards the finalization of the entire mining line. This project solidifies Algeria's position as a leader in African infrastructure development and marks a decisive step towards economic diversification and sovereignty. The bridge is more than concrete and steel; it is a pathway to a more prosperous and industrially independent future for the nation.
